Kindergarten, formerly known as nursery and kindergarten, is a kind of pre-school education institution, which is used for centralized care and education of children, and usually accepts children from three to six years old. The task of kindergarten is to remove the constraints of time, space and environment when the family is cultivating children, so that the children can develop physically, intellectually and emotionally healthily. It can be said that kindergarten is a happy world for children, which can help children to spend their childhood healthily and happily, not only to learn knowledge, but also to get in touch with collective life from childhood. As the foundation of the whole education system, kindergarten education is the preparatory education for children (complete and healthy personality, good behavior habits and preliminary natural and social common sense).
